Beitknown that We, lll'nn'sni, Tobin and MARTIN Tonia, citizens of the United States, 'residing at New `Prague, in the county ot "Lesueur' and lState ,of lviinnesota, have,..i.n Vented certain' newl nd'useful Improve ments in Tractor-Governors; and we' do declare the following tohe a full7 cleaig'and exact .description of the invention7 such as 10 will enlole;others skilled in the art to which it appertainswto'inalreand use tlie saine.

A vertical arm is provided with la flange 8 at its upper end vwhich issecured by Iefip screws 9 or otherpreferred means to the'ljot-y toni of the header (i, and the lower endof 'said arm vcarries a horizontal bearing l0 Vwhich "extends longitudinally of the inachine'.v -Rotateble in 4*the bearing l0 is a tu-` Avloular shaft'llhaving on its front end a grooved pulley I2, which is driven by a lloelt "lirom a similar pulley 14 which is in turnS driven by theffan belt 4.

The bell crank 25 is i'ulcrumed on "the upperlendofve stud 29 which is tapped into one of the cap screws 30.,4 which screw holds the lcylinder head of the motor inplace.'

Froi'ntlie foregoing. taken in connection 4yvitli the-accompanying drawings. it xvill 'be seentliat although Your invention is of 4extreniely simple and inexpensive nature., and

may be easily attatched to the tractor, it

will'behighly eiiicient in governing the inotor speed, both .when the machine is used for traction purposes and as a stationary en,-

- gine. Since probably the best resultsya're obtainable'froni the details shown and de scribed. and by attaching the severalgparts 'in the manner. disclosed, these features are preferably folloyvechbut We yvish'it understood that yvitliin the scope ofthe invention as claimed, considerable latitude is'alloyved for j nia'kingl numerous minor changes.

@We claim:

ll. In a governing device for tractors, the

combination with the tractor motor having fa forwardly extending rotary shaft, a carbureter, and a rock shaft for extending longitudinally of the inotor for controlling said (,arbureterz of a centrifugal governor mounted adjacent the front end of said nio@ tor and driven from said rotary shaft. a rod parallel with said rock shaft and longitudinally shifta'ble by sa'id governor. and means connecting said rod and rock shaft .for .turning the latter' from the former.

the. motor and driven from said rotaiiysliaft, 'a push rod niounted-slidably in said' ,tu-bular shaft, a \veight `ed governor arm carried by the rear endfofisaid tubulars'haft tory shitting said push'rod, an arm rigidlygde:

pending from 'the frontend of said push.

' rod in ad. anceof said vtubular shaft, a con'- trol rod parallel Withsaid rock shaft-land w extending rearwardly from the outer' end'of' said arni,\andmeans connecting said control f .rod vand saicljrock shi latter from the ormer The combinatioii- ,y having a forvvarcllyexter a carbureter, 'and a contr caibureter, said motor? a tract'or.,inotor "g rotary shaft,

g a detachable cylinder head secured in place bycap-s'c'rews; v

connecting. said cont-rol member 1with -'said' bell crank. f

l. A governing attachment for tractors comprising-a pulley adapted to be driven by the-usual tia'n belt pulley, a bearing having any attaching b'acket for mounting ,it longitudinally at the front end of the motor, a tubular: shaft rotatable in said bearing and carrying a pulley on its front end, a belt driving said last named )alley from the aforesaidipulley, a Weighte governor arm 'mounted l(on the rear end of said tubular shaft, a push rod slidable in said tubular shaft and operated by said governor arm, a lateral arm extending rigidly from the front lend of s aid push rod', a control rod parallel with said rock shaft and extending rearwardly lvfrom the outer end of .said arm, a bell crank connected at one end with the rear end of said Control rod, a'link extending from the other end of said\ bell crank. a crank arm connected to said link and adapt-ed for attachment to the carbureter control shaft. and means' for fulcruming said bell crank on the tractor motor.

ln testimony whereof we have hereunto set our lwinds.'
